1. Unprotected exposure to the sun's rays is a factor in the development of skin cancer. Which of the following is an example of empirical evidence that supports this
hypothesis?
A. a model of a skin cell showing where DNA is in the cell.
B. a skin cancer survivor's recollection that he had a bad sunburn as a child.
C. an advertisement for a sun block product that claims it protects skin against ultraviolet
rays.
D. data demonstrating a relationship between the amount of sun exposure and incidences
of skin cancer.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.

the answer is 100. i just did this lesson and got a 100% on it. : )
